Omni San Francisco's ENERGY STAR score of 55 compares with an average of 78 across the 790 that report a score; it scores higher than 14% of them and lower than 86%. Its site EUI of 93.4 kBtu/ft² is about 90% above the average of 49.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.8 kgCO₂e/ft² is about twice the group average of 2.7 kgCO₂e/ft².
At 250,000 sq ft, it is about 133% above the average floor area of 107,408 sq ft for those buildings. It was built in 1927, 14 years earlier than the group's average year built (1941).

How has Omni San Francisco's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Omni San Francisco, covering report years 2011–2025. Its ENERGY STAR score went from 27 in 2011 to 55 in 2025 (+28 points); its best year on file was 2021, at 83. Site EUI moved from 105.7 kBtu/ft² (2011) to 93.4 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 1,866 tCO₂e to 1,451 tCO₂e over the same span (down 22%).
What does an ENERGY STAR score of 55 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 55 means the building performs better than about 55% of its national peers. BuildingCensus bands the score into report-card grades; 55 falls in band C — below median (55–69). It sits 20 points below 75, the threshold for ENERGY STAR certification. In San Francisco, 73% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Omni San Francisco's 93.4 kBtu/ft² across 250,000 sq ft works out to about 23.4 billion Btu (6,843 MWh-equivalent) in 2025. Its source EUI of 167.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,557,218 kWh of electricity and 14,385 therms of natural gas for the year.
Which law requires Omni San Francisco to report its energy use?
Omni San Francisco reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record sf:0240/003:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
